This invention relates to mail bags especially designed for air mail,an'object being to provide a bag which will be fireproof, water-proofand non-sinkable, so that the contents of the bag will be pre-V servedin the event of an accident to the carrying plane resulting from fire,or otherthe means for preventing the bag from sinking.

Referring tov the drawings in detail wherein like characters ofreference denote corresponding parts, the reference character 10indicates a mail bag which is made of fireproof-material, so that thebag may be used for air mail and the contents preserved in-the event ofaccident by fire. The bag is further water proofcso that the contents-ofthe bag will alsobe protected from the action of water should accidentoccur when the plane'is flying over a-body of water; For'this purpose,the bag is constructed of an outerfire-proof bagand an inner water-proofbag. the outer bag mayconslst of asbestos cloth such as is used forfire-proof curtains in theaters; This cloth usually consists ofasbestosyhavingits threadsor strands woven upon copper wire. A bag ofthis character would not only be fire proof, but of great strength dueto the wire reinforcement. Theopen end ofthe outer bag 10 is preferablyprovided with a flap 11 extending the opposite edge of the bag; [Eyes orstaples 12 extending from this last referred to edge pass throughgrommets or eyelets The material for from one edge, this flap is turneddown over 13, while a rod or stifl' wire cable 14 is passed through theeyes or staples 12 ay is secured in place by means of a lock 15,

'If desired, a flexible cable or draw-string maybe-passed directlythrough the grommets, in this case both sides of the ba' g would be ofthe same 7 length with no flag on the bags.

The bagmay also be provided with an eye 16, the shank 17 of which issecured to the bag,'sothat the said bag may be sup-,5;

ported upon a rod or other suitable device arranged beneath the bottomor upon opposite sides of the carrying plane. Also, due

to the flexibility of the bag structure," the latter may be folded so asto occupy a rela- .f'

tively small space in the event that the bag is not entirely filled withmail matter.

For the purpose of rendering the bag non-sinkable, a flexible member 18extends around the bag preferably near each end thereof. This member isthreaded through suitable eyelets 19 and carries a plurality of buoyantelements 20. These elements may consist of cork or balsa wood, or theymay be hollow copper elements having openings .therethrough for thepassage of the flexible member. M g p I k elements are shown at oppositeends of the While the buoyant bag', their number and arrangement mayvary in accordance with the weight of the contents of the bag. Thebuoyant elements however are preferably arranged so that the bag willfloat mouth upward.

In Figure 5 a spherical "opper or other metallic element-21 isillustrated, a similar element 22 of substantially oval-shape is shownin Figure 6.

The inner bag which is indicated at 21 may be made of any suitablematerial, such 7 as oiled canvas, silk, or rubber coat fabric of thecharacter used in the manufacture of. raincoats.

The bag 21 isfolded a suitable number of times as indicated at 22"? soas to prevent the entrance of water into the bag. Means are-provided forholding the bag closed, and in Figures 7, 8, and 9, this means consistsof a pair of clampingstrips 23 whose adjacent ends are connected bybolts 24; and thumbnuts 25. The folded mouth of the bag may thus betightly and securelyclosed and inserted Within the outer fireproof bag10. By making the bags 10 and 21?.sepa- I rate, and by providingseparate closing means for each of thebags, theinnerwaterproof bag maybe securely closed before being placed'within the outer fire-proof bagso that danger of leakage in through the mouth of the bag 21? will beprevented.

In FigureslO and 11, a spring influenced clamp 26 is substituted for theclosing means shown in Figures 7 8, and 9. i v

In Figures 12 and 18, the mouthof the bag is closed by the Well knownslidable h oug w i the cable th aded, and

buoyant elements carried by each cable and disposed between theconfronting portions of each of the eyelets. e

2. The combination with a mail bag, of flexible cable 'members extendingaround the bag, spacing means for attaching the cable members to thebag, buoyant elements carried byeach cable member and disposed betweenthe confronting portions of each of the spacing means, and a closure forsaid 1 bag .
